AUTOMATTC DRAZNING DEVICE.

Application filed June 29, 1512.

To aZZ whom it may concern:

Be it known that I, EDMUND NINARsKY, a subject of the Emperor ofGermany, residing at Brunswick, Germany, have invented certain new anduseful Improvements in Muscle vial-lung Devices; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as'will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

This invention relates to automatic drain ing devices such as areemployed for t-rap ping the water from steam pipes and automaticallydischarging this water from time to time.

The object of the present invention is to provide an automatic drainingdevice which shall be free of all internal levers and jointed parts, andwhich may be readily blown through for the purposes of cleaning andclearing the passages. This and other features of the invention will bemore readily understood from the following description of one convenientform illustrated by way of example in the accompanying drawing, hichshows a cross section through an automatic draining device according tothis invention.

The draining device embodies a receptacle a, which, in the present case,is provided with a conical bottom I), so as to act as a guide to thegravity valves hereinafter described. At the bottom of the conical base6, there is arranged a valve seat 0, on which a plurality of gravityvalves, shown as ball valves d, are arranged to rest. The ball valves(5, ;,c ontrol outlet passages 6, having cupped topjsf T to flt the ballvalves. The valve seating plate 0, is provided with an upstandingclrcular projection c, which" takes into a pipe or tube h, fixed to thebottom of a float f, in the chamber or recepta cle a. The tube or pipeh, has a flared or expanded end it, which takes under the ball valves d.It will be seen that the ball valves are all separate and in no wayconnected to the tube It. The tube It, thus forms an independent memberfixed to the float and arranged centrally to the symmetrically disposedball valves. hen the conical bot tom 12, and the receptacle (1, becomesufli- Specification of Letters Patent.

ciently filled with water the float f, rises and the flared end of thetube h, engages loosely with the ball valves. The ball valves are thuspressed to the side against the conical walls of the bottom I), and whenthe float drops the conical walls guide the ball valves on to theirseats. The Water passing through the passages e, finds its outlet atb.

In order to blow the apparatus through for cleaning purposes thefollowing arrangement is provided. On the top of the float f, there is astem g, over which may be passed a piston or the like 9. This piston maybe fixed on to the stem in any convenient manner or formed in onetherewith. The piston g, is adapted to fit into a sleeve is, over whichthere is arranged a snifting valve i. With this arrangement it will beseen that when the shifting valve is open the pressure on the sphericalfloat f, is uneven. Thus the entire pressure is operating on the lowerhalf, whereas on the upper half the area on which the pressure is actingis reduced by the area of the piston 9. Thus, if the area of the pistong, were one squarecentimeter and the steam pressure were fiveatmospheres, there would be an excess upward pressure on the float f, offive kilograms. This upward force would overcome the weight of thesphere and the resistance of the valves to being rolled up the inclinedsides and the friction of the piston g with the sleeve 0. It is obviousthat the magnitude of this upward force is dependent on the product ofthe pressure per unit of area and the area of the piston g, and it isread ily understood that other things being equal, a smaller pressureper unit of area will require the piston g to be of larger area than ifthe pressure were larger. In order that the draining device may beeasily altered so as to suit a lower pressure, the piston g, which isremovable, can be replaced by a larger piston, the sleeve 70, beingbored out passage and in cases where small parts of solid matter, suchas scale, have to be passed the ball valves cl, may completely roll backso as to give a free uninterrupted passage. In such cases the conicalbottom guides the balls back on to their seats as they fall by gravitywhen the float descends.

I claim:

1. An automatic draining device, having in combination a receptacle, aplurality of separate outlet valves located symmetrically at the lowerend of said receptacle, a float in said receptacle, a member fixed tosaid float and arranged centrally to, but independent of, said valves toengage the same loosely and open them when the float rises.

2. An automatic draining device having in combination a receptacle, aconical base on said receptacle, a plurality of gravity valves locatedin a circle at the lower narrow end of said base, a float in saidreceptacle, a member fixed to said float and arranged centrally to, butindependent of, said valves to engage the same loosely and open themwhen the float rises, substantially as described.

3. An automatic draining device having in combination a receptacle, afloat therein, an outlet at the lower end thereof, a plurality ofsymmetrically disposed ball valves controlling said outlet, an expandedtube carried by said float and having its expanded end located centrallyto engage and open said ball valves when the float rises.

4. An automatic draining device having in combination a receptacle, afloat therein, a conical base on said receptacle, an outlet from thelower narrow end of said conical base, a plurality of ball valvesarranged in a circle at the lower end of said base and controlling saidoutlet, a tube carried by said float and having a flared end takingunder said ball valves to spread and open the same when the float rises.

5. An automatic draining device having in combination a receptacle, avfloat therein, a conical base on said receptacle, an outlet from thelower narrow end of said conical base, a plurality of ball valvesarranged. in

a circle at; the lower end of said base and controlling/said outlet,tube carried by saidfloat Iand having a flared end taking under-"saidball valves to spread and open the samev when the float rises, and afixed" in said receptacle, a member fixed to said float and arrangedcentrally to, but independent of said valves, means for raising saidfloat for cleaning purposes, comprising a stem on said float, a sleeveengaging over said stem, said stem fitting tightly in said sleeve and asnifting valve for controlling the outlet of fluid from said sleeveabove the top of the aforesaid stem, substantially as and for thepurpose hereinbefore set forth.

7. An automatic draining device, having in combination, a receptacle, aplurality of separate outlet valves, located symmetrically at the lowerend of said receptacle, a float in said receptacle, a member fixed tosaid float and arranged centrally to, but independent of said valves,means for raising said float, for cleaning purposes, comprising a stemon said float, a removable piston onsaid stem, a sleeve engaging oversaid piston, said piston fitting tightly in said sleeve and a sniftingvalve for controlling the outlet of fluid from said sleeve above the topof the aforesaid piston, substantiallv as and for the purposehereinbefore set forth.

8. An automatic draining device having in combination a receptacle, aconical base on said receptacle, an outlet from the lower narrow end ofsaid conical base, a plurality of ball valves located in a circle at thelower end of said conical base and controlling said outlet, a float insaid receptacle, a tube fixed to said receptacle and having a flared endlocated to engage and spread said ball valves when said float rises, astem on the top of said float, a sleeve in which said stem fits and asnitting valve located on said sleeve above said stem.

9- An automatic draining device comprising a receptacle having aninclined bottom, said bottom having an opening, a ball valve normallyclosing the opening, and a float mounted in the receptacle, said floathaving a projection which loosely engages the under portion of the ballvalve to roll the latter up the inclined wall and uncover the openingwhen the float rises, the ball valve rolling down the inclined wall andover the opening when the float is lowered.
